A 1ppm Ammonia sensor demonstrated

We continue our fruitful collaboration with Prof Eddaoudi and report a MOF based ammonia sensor exhibiting excellent performance for simulated breathing system in the presence of a mixture of humidity and carbon dioxide.  The sensor can detect NH3 at concentrations down to 1ppm with a detection limit of 100ppb at room temperature.
